Specification forming part of Letters Patent No. lSLQB, dated Septemberl0, 1872.

To all whom t may concern: A

Be it known that I, CHARLEs DECKER, of the city, county, and State ofNew York, have invented a new and "Improved Presser-Foot for SewingMachine; and I do hereby declare the following to be a full, clear, andexact description thereof, which will enable those skilled in the art tomake and use the same, reference beinghad to the accompanying drawingforming part of this specication, in which drawing- Figure l representsa plan or top view of Fig. 2 is a side view of the same. Fig'. 3 is atransverse section of the same in the plane aux, Fig. l.

Similar letters indicate corresponding parts.

This invention consists in the arrangement of a serrated or roughsurface roller, which has its bearings in a slide that tits thepresser-foot, said roller being situated behind an aperture made in theslide for the passage of the needle in such a manner that by said rollerthe operation of feeding the material through the machine is materiallyfacilitated, and at the same time the roller can be readily removedwhenever it is desirable. Said roller is provided with a needle-groove,so that the same can be set as close to the needle as may be required toinsure its perfect action.

In the drawing, the letter A designates a presser-foot, of any desirableform or construction, to correspond to'the class of sewing-machines forwhich the same is to be used. This presser-foot is made bifurcated, andbetween its prongs is tted a slide, B, .which forms the bearings for arough surface-roller, C. This roller is close behind a hole, a, in theslide B, said hole beingintended for the passage of the needle 5 andwhen the presser-foot is in position and allowed to bear down upon thematerial to be sewed, the'roller C co-operates with the feed-dog orfeed-wheel of the sewingmachine, and assists in passing said materialthrough under the needle; and furthermore, on account of its locationback of the needle, said roller draws the material awayfrom the needle,and the regularity of the feeding operation is insured. In the roller Cis made a deep semicircular groove, b, corresponding in width andposition to the needle-hole a in the slide B; a-nd by these means I amenabled to bring-the roller C close to the needle-hole, and to allowsaid roller to act on the material to be sewed in close proximity to theneedle. The slide B is provided with a large recess, c, in front of theneedle-hole, so that the material to be sewed can be observed close upto the needle, and the person operating the sewing-machine can watch theprogress of the work with ease and facility. If the roller C is not tobe used the slide B can be readily removed and another device can beinserted into the presserfoot, so that my roller-slide does notinterfere with any other operation that may have to be performed on thesewing-machine.

What I claim as new, and desire to secure by Letters Patent, is-

The combination, with a presser-foot, of a slidecarrying a roller, whichis situated behind a hole made in said slide for the passage of theneedle, the whole being constructed and operating substantially in themanner herein shown and described.
